Division (3)

Member States shall calculate the cumulated carbon cost of measures/packages/variants over the calculation period by taking the sum of the annual greenhouse gas emissions multiplied by the expected prices per tonne CO₂ equivalent of greenhouse gas emission allowances in every year issued, using as a minimum lower bound initially at least EUR 20 per tonne of CO₂ equivalent until 2025, EUR 35 until 2030 and EUR 50 beyond 2030 in line with current Commission projected ETS carbon price scenarios (measured in real and constant prices EUR 2008, to be adapted to the calculation dates and methodology chosen). Updated scenarios shall be taken into account every time a review of the cost-optimal calculations is carried out.
